The design of plain foundation slabs is carried out by keeping the ratio of foundation depth to foundation projection (overhang), The following applies:
| d | Foundation depth |
| a | Foundation projection from the column face |
| σgd | Design value of the ground pressure |
| fctd,pl | Design value of concrete axial tensile strength |
The intermediate values of the described design are documented in detail in the result windows.
Mr. Meierhofer is the development leader of programs for concrete structures and is available for the customer support team in case of questions related to reinforced and prestressed concrete design.

CYS EN 1992-1-1:2004/NA:2009 | CYS EN 1997‑1/NA:2004 In addition to the National Annexes (NA) listed above, you can also define a specific NA, applying user‑defined limit values and parameters.
Foundations are assigned graphically by selecting supports using the [Select] function in the graphical user interface of RFEM/RSTAB and by specifying the load cases to be designed. You can define all other foundation details quickly and easily in clearly arranged input windows.
In addition to all support forces from RFEM/RSTAB, you can specify further loads to be considered when dimensioning the foundations. The following additional loadings are available:
The program creates a reinforcement proposal for the top and the bottom plate reinforcement. The program searches automatically for the most favorable reinforcement combination, with a mat and added rebars. If required, the rebars are distributed across two reinforcement areas by curtailment. It is possible to modify the reinforcement proposal individually by:
You can display the foundation in excellent rendering quality, including reinforcement. In the rendering, as well as in up to seven different dimensioned reinforcement drawings ready for construction, the module provides a solution proposal for bucket design. It is possible to modify the number, position, diameter, and spacing of used rebars here as well. You can also determine the shape of the applied links.
The dimensions of the foundation plate and bucket can be determined by the add-on module, or can be user-defined. Clearly arranged windows display the results of each performed design, including all intermediate values. They are covered in a reduced printout report providing a verifiable structural analysis.
It is possible to perform the following designs:
Foundation and bucket dimensions can be user-defined or determined by the module. You can edit the determined reinforcement manually. In this case, the designs are updated automatically.
Main Program
The new generation of 3D FEA software is used for the structural analysis of members, surfaces, and solids.
Add-On
The Concrete Design add-on allows for various design checks according to international standards. You can design members, surfaces, and columns, as well as perform punching and deformation analyses.
Add-On
The Construction Stages Analysis (CSA) add-on allows for considering the construction process of structures (member, surface, and solid structures) in RFEM.
Add-On
In RFEM, the Geotechnical Analysis add-on uses properties from soil samples to determine the soil body to be analyzed. The accurate determination of soil conditions significantly affects the quality of the structural analysis of buildings.
Add-On
The Modal Analysis add-on allows for the calculation of eigenvalues, natural frequencies, and natural periods for member, surface, and solid models.
Add-On
The Response Spectrum Analysis add-on performs seismic analysis using multi-modal response spectrum analysis. The spectra required for this can be created in compliance with the standards or can be user-defined. The equivalent static forces are generated from them. The add-on includes an extensive library of accelerograms from seismic zones that can be used to generate the response spectra.
Add-On
Using the Pushover Analysis add-on, you can analyze the seismic actions on a particular building, and thus assess whether the building can withstand an earthquake.
Add-On
The Building Model add-on for RFEM allows you to define and manipulate a building using stories. The stories can be adjusted in many ways afterwards. The information about stories and the entire model (center of gravity) is displayed in tables and graphics.
Add-On
The Masonry Design add-on for RFEM allows you to design masonry using the finite element method. It was developed as part of the research project titled DDMaS – Digitizing the Design of Masonry Structures. The material model represents the nonlinear behavior of the brick-mortar combination in the form of macro-modeling.
